This will mean an # extra stack switch when processing some interrupts, but should # significantly reduce the likelihood of stack overflow. # # It also means the softirq stack will be used for running softirqs from # other interrupts that don't use the hard irq stack, eg. timer interrupts. # # Fixes: 1b1b6a6f4cc0 ("powerpc: handle irq_enter/irq_exit in interrupt handler wrappers") # Cc: stable@vger.kernel.org # v5.12+ # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20220525032639.1947280-1-mpe@ellerman.id.au # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 0c69905577499b8e057767e08a763443ebf504fb # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64e_defconfig+KEXEC_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64e_defconfig # Added to kconfig CONFIG_KEXEC=y # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64e_defconfig+KEXEC_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64e_defconfig+KEXEC_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:3056:warning: override: reassigning to symbol KEXEC # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64e_defconfig+KEXEC_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-fixes_ppc64e_defconfig+KEXEC_powerpc-gcc5 # Build took: 0:00:54.013794
